One of the biggest providers of domain names and web hosting in Europe is changing hands today. One.com, which has around 1.5 million customers mainly across the north of the region, has been sold by private equity firm Accel-KKR to Cinven, another PE player that focuses on investments in Europe.

Terms of the deal are not being disclosed, but as a rough guide, Cinven once owned and sold another European hosting provider of comparable size: it acquired Host Europe Group in 2013 for $668 million and then sold it in 2016 for $1.8 billion to GoDaddy two years ago almost to the day. At the time of the sale, Host Europe Group also had about 1.5 million customers.

One.com and its business segment represent a significant, if not wildly evolving, part of the tech landscape: for as long as businesses and consumers continue to use the web, there will be a need for companies who sell and host domain names and provide services around that.

With a catchy domain name of its own, One.com has been riding the wave of that solidity of purpose for several years already. KKR-Accel says that organic growth at the company has been accelerating at a rate of 20 percent and that revenues under its four-year ownership doubled to €60 million ($69 million) with profitability growing 50x on a marketing pitch in which it positions itself as the ‘budget’ option to businesses.

“The vision of One.com since its founding has been to deliver value-added and easy-to-use solutions to small- and medium-sized businesses and prosumers,” said Jacob Jensen, Founder and CEO of One.com, in a statement. He is staying on to continue leading the company.

Cinven says it is interested in growth the business by way of acquisition, specifically: “There are opportunities to accelerate the growth of the business organically and through acquisition.”

In other words, expect some consolidation moves in the future where some of the smaller providers in Europe potentially get gobbled up to create a bigger entity with better economies of scale. That’s needed not just because GoDaddy has ramped up its presence here, but because the likes of Amazon has only grown in stature and provides a number of other services to users to make its offerings more sticky.

“We are very excited to invest in One.com alongside Jacob. It is a high quality business with an attractive brand and scalable technology platform, operating in a market with structural growth drivers,” said Thomas Railhac, Partner at Cinven, in a statement. “This is a subsector we know well through Cinven’s successful investment in HEG in Fund 5, continuing to invest in both the organic growth story and targeted acquisitions.”
